Does the 2016 Acura RDX require premium gas?

The 2016 Acura RDX is designed to run best on premium unleaded gasoline, but it does not prohibit regular gas. Premium is strongly recommended for optimal power and performance, while regular can be used in a pinch with noticeable trade-offs in throttle response and efficiency.

What the manual says

Recommended octane level

According to Acura’s guidance for the 2016 RDX, premium unleaded gasoline is recommended to achieve the vehicle’s full performance. This typically means an octane rating of 91 or higher in markets where that rating is standard for premium fuel. If premium gasoline is unavailable, you can use regular unleaded gasoline, but expect reduced power and responsiveness.

• Premium unleaded gasoline is recommended for optimal performance.


• Regular unleaded gasoline (87 octane) can be used if premium is unavailable, but performance and acceleration may be reduced.


• In demanding conditions (hot weather, steep climbs, or high-load driving), higher-octane fuel helps maintain power.


• Check your owner's manual for your region’s exact octane guidance and any notes on ethanol content.

Using premium gasoline provides the best balance of power, responsiveness, and efficiency. Regular gasoline is acceptable in a pinch, but drivers should anticipate a noticeable impact on performance under certain driving conditions.

Practical considerations for drivers

Using regular gas in daily driving

Here are practical implications to consider when deciding which fuel to use in everyday driving of the 2016 RDX.

• Expect reduced acceleration and throttle response when operating on regular gasoline instead of premium.


• Regular fuel can lead to lower fuel economy, especially during spirited driving or when carrying a heavy load.


• The engine’s knock sensor will adjust timing to prevent knocking, but sustained use of lower-octane fuel may blunt performance over time.


• For optimal and consistent performance, plan fuel up with premium when possible, particularly for highway or performance driving.

In practice, regular gas can work for daily commuting, but premium remains the best option for consistent performance and efficiency across driving conditions.

Summary

Bottom line: The 2016 Acura RDX does not strictly require premium gas, but premium unleaded gasoline (around 91 octane or higher) is recommended for peak performance. Regular gas is allowed if premium isn’t available, yet it comes with measurable compromises in power, responsiveness, and efficiency. Always consult the owner’s manual for your specific market’s octane guidance and ethanol content considerations.

Can I put regular gas in my Acura RDX?

No, an Acura RDX is not designed to take regular gas; it is highly recommended to use premium gasoline for optimal performance, efficiency, and longevity. While the engine can run on regular fuel, it will do so less efficiently, potentially leading to reduced horsepower, lower fuel economy, and engine knocking. Using premium fuel ensures the engine runs smoothly as it is designed to. 
What to do if you've been using regular gas

• You can switch to premium fuel, and the engine computer will adjust to accommodate the change.
• It is best to stick with one type of fuel once you make the switch.
• Using regular gas in the long term can cause deposits to build up and potentially damage the engine over time. 

Why premium is recommended

• Acura's turbocharged engines require higher octane fuel for peak performance. 
• Premium fuel prevents pre-ignition, which can cause engine knocking and rattling. 
• Premium fuel will result in better fuel economy and longevity for your engine.

Years to be cautious about

• 2013-2015: These years can have transmission issues like rough shifting and slipping, and some models may have engine oil leaks. 
• 2015: In addition to transmission problems, this model year had issues with airbags and the soy-based wiring insulation attracted animals. 
• 2018: Reported transmission problems and potential engine issues like head gasket or timing chain problems have been noted. 
• 2019: This is widely considered the least reliable model year, particularly because it was the first year of a new generation. Owners have reported engine stalling, power loss, and issues with the rear glass shattering. 
• 2021: This year experienced issues with the transmission, brakes, and engine stalling due to a potential intercooler design flaw that could let moisture into the engine. 

What to do if buying used

• Thoroughly inspect any used model for the specific issues mentioned above. 
• If considering one of these years, have a trusted mechanic perform a pre-purchase inspection. 
• Check for service records and recall history.
